Our focus to the end of the year is cell to cell communication and that starts with the cell membrane that defines the inside of the cell (intracellular) and the outside of the cell (extracellular). The cell membrane determines what components can enter or leave the living space (intracellular) and it also is responsible for the protruding protein receptors that allow for chemical messengers to communicate.

4: Water potential
3/18 – Thursday – “C” Day – Homework:
1. Please read below:
Tonight we are learning how water and why water passively diffuses into and out of cells through integral transmembrane proteins called aquaporins. This diffusion of water is specifically called osmosis and its ability to move across the cell membrane is based on a mathematical concept called water potential (ψ). Do not get intimidated by the ψ symbol.
The greater the ability for water to reach the aquaporins at the cell membrane the greater the ability the water has to perform osmosis. We say that in this instance water has high water potential.
The highest water potential water can have is zero. This would be with water with no solute particles.
ψ water = 0
The lower the ability for water reach the aquaporins at the cell membrane, the lower the ability water has to perform osmosis. We say that in this instance water has low water potential. The lowest water potential will have the most negative number.
ψ water = negative
The factors that determine the ability of water to undergo movement across a membrane include the dissolved particles in the solution called the solute potential ψsolute (solute potential) and ψpressure (pressure potential). Pressure potential can be both positive or negative depending if the pressure helps water get to the membrane (positive) or if it prevents it (negative).
ψ water = ψ pressure + ψ solute
Dissolved particles get in the way of water reaching the aquaporins in the cell membrane and thus solute potential is always negative.
ψsolute = – iCRT
i = the number of particles the dissolved particle breaks apart into.
Example: NaCl —-> Na+ + Cl– (2 particles)
So NaCl (table salt) has an i = 2
C = Concentration value
R = Gas Law Constant
T = Temperature (kelvin scale)
There is movement of water in both directions BUT there is OVERALL NET movement of water TO THE Right!
THis is because there is higher water potential on the left side of the semipermeable membrane AND there is Lower water potential on the right side due the dissolved particles (getting in the way of water reaching the membrane).
The formulas for water potential and solute potential are located in your reference table:

1. Water potential = presentation slides 1 – 16
2. Homework review – Water potential worksheet p.pdf . It was emailed back to you last today.
Isotonic / Hypotonic / Hypertonic
equilibrium = water potential extra cellular = water potential intracellular
Osmosis vs. diffusion
Active vs. Passive transport
Last nights Key:
3. Cell Diffusion Lab –
*ORDER PAINTED L FOR WEEK 7 or 8 ARRIVE MONDAY.
1. Diffusion Lab – Surface area to volume ratio
2. Diffusion races – design a cell – Winner has the greatest mass to second ratio.
Water potential presentation:
Why do we need cells? Why are they so small small? Why are prokaryotes smaller than eukaryotes?
CELL RACES RULES:
- No donut-like holes through the agar cell — cell membranes cannot sustain that shape.
- No poking, prodding, touching beaker containing agar cell in vinegar.
- Teacher determines when 100% diffusion takes place.
- Students mass agar at conclusion of race…cell must not break when handled. Disqualification if cell breaks upon massing (although you can be a bit lenient here).
- No slivers or shaved cells. Cells must be at least 1 cm in width.
- Winner = highest ratio of mass divided by time.
3/19 – Friday – “D” Day – Homework:
FULL REMOTE STUDENTS: I have posted a video of the agar shapes that the students viewed for the lab we were working on. I apologize that I did not give you live look at it today..
1. Complete the Photosynthesis Lab Write-up.
2. Please complete Water Potential 2 worksheet fixed.pdf and review with the key.
Please skip questions (i) on page 1 and 2.
3. Please complete second water potential form below.
*Also there is water potential review lecture that I posted (below the form) if what I did in class is getting you down like a very concentrated solution. 🙂
